[pve-devel] [PATCH manager 1/1] ui: allow configuring and live migration of mapped pci resources

[Dominik Csapak <d.csapak@proxmox.com>]

if the hardware/driver is capable, the admin can now mark a pci device
as 'live-migration-capable', which then tries enabling live migration
for such devices.

mark it as experimental when configuring and in the migrate window
